Melissa's Tech Corner

 Programming can seem overwhelming. There are lots of languages out there.  Here are some of the ones that are considered by IEEE Spectrum's interactive rankings to be some of the top languages to learn. They are Python, C++, Swift, JavaScript, and Java. The list goes on.  The purpose of this article is to focus on Java. Java is considered a multi-platform language, which means it can be used across many program platforms. It is an Object-Oriented program, and the main concepts are Abstraction, Encapsulation, Polymorphism, and Inheritance. It is considered a secure way to develop applications on the internet.  There are several open-source applications that can be used for installing the open-source applications used in compiling Java programs. They are NetBeans ( http://netbeans.org ) and Eclipse ( http://www.elicpse.org ), just to name a few. I prefer NetBeans. Installation is straightforward and simple.  Here is the resource I used when downloading NetBeans https://netbeans.apac

  TECH TOPIC CONNECTION: NETWORK SECURITY In this final blog post cataloging my efforts through my TEC101 course, we'll delve into the crucial realm of network security and explore its intricate connection to the fundamental aspects of information technology covered throughout this course. Network security is an indispensable component of the IT landscape, as it safeguards data, systems, and communications from unauthorized access and malicious threats. To comprehend its significance, let's dissect its relationship with key IT concepts, hardware components, programming languages, application software, database management, and network architecture, management, and security. Network Security and Information Technology Concepts At its core, network security aligns with the foundational concepts of information technology. It revolves around the protection of data and systems, ensuring the confidentiality, integrity, and availability of information. This resonates with the fundament

THE CRITICAL IMPORTANCE OF INFORMATION AND SYSTEM SECURITY In the digital era, the security of information and systems has become a paramount concern for individuals and organizations alike. As the world becomes increasingly interconnected through computer networks and information systems, it is vital to adopt a proactive stance in safeguarding data integrity, confidentiality, and system reliability. This blog post underscores the profound significance of information and system security and delves deeper into pivotal computer security incidents: vulnerabilities and computer viruses. Ping Commands and Potential Threats: Ping Flood Attack: The ping flood attack is characterized by the inundation of a target system with an excessive volume of ping requests. These requests, often initiated from a botnet, overwhelm the target's network infrastructure, and consume its available bandwidth. The consequences are manifest in network disruptions or significant slowdowns, thereby rendering ser

COMPUTERS IN THE WORKPLACE   The Role of Computers in Healthcare: Current and Future Impact In the healthcare industry, computers play a vital role in transforming patient care, administrative processes, research, and overall operational efficiency. The integration of information technology has led to enhanced medical diagnoses, improved patient outcomes, streamlined workflows, and the collection of vast amounts of data for research and analysis. Patient care devices, ranging from wearable health trackers to advanced diagnostic equipment, have further revolutionized healthcare delivery. Current Functions of Computers in Healthcare: Electronic Health Records (EHRs):  Computers facilitate the creation, storage, and accessibility of patient health records, ensuring accurate and efficient management of patient data. Medical Imaging and Diagnostics:  Sophisticated imaging equipment, such as MRI and CT scanners, rely on powerful computing systems for image processing and interpretation. Tele

TRAVELING THROUGH A NETWORK Using Ping and Traceroute to Explore Network Paths In the world of networking, understanding how packets of information travel through networks is essential for diagnosing and troubleshooting issues. Ping and traceroute commands are valuable tools that provide insights into the paths that data takes as it navigates the internet. In this activity, I used these commands to explore the journey of data packets and gain a better understanding of network connectivity. Ping Activity: I started by using the ping command to test the connectivity to Google.com. The results showed that a certain number of packets were sent, received, and lost. The response speeds varied, showcasing a range of milliseconds. This initial ping test demonstrated the roundtrip time between my computer and Google's servers. I then extended the ping test to two other websites hosted in different regions of the world. The results highlighted differences in response times due to the geograp
